Undoubtedly one of the best science fiction series of all time. Two outcasts roam a post apocalyptic world, encountering various people and Orwellian societies living in isolation from each other. Reminds one to an extent of The Prisoner, but with a take on modern day society, rather than the individual's dehumanization by it. Like the prisoner, this series only has a few episodes, but each episode is set in an entirely different set.
